Abstract

An acoustooptic phased array antenna beamformer with independent phase and carrier control capability is experimentally demonstrated using single sideband signals with frequencies w_c + w_o and w_c w_o to drive the two acoustooptic devices, respectively. Varying w_c controls the antenna carrier (2w_c), while changing w_o only effects the phase. 0–2 x phase control is achieved using 0–340 kHz change in w _o, with the carrier fixed at 120 MHz using w_c = 60 MHz. A dynamic range of 66.6 dB at 2 MHz and carrier-to-noise of 126.9 dB/Hz at 2 MHz is measured. This beamformer can provide wide antenna tunable bandwidth and intrapulse beam forming.
